The Use of Recrystallised RDX in Cast RDX/TNT Compositions,
Abstract
The particle size of RDX recrystallised from cyclohexanone (Grade A Class 1) is much larger than that of milled and boiled RDX (Grade B Class 1), and as a consequence, the recrystallised RDX is subject to a larger sedimentation during casting of RDX/TNT/Beeswax compositions. However, this sedimentation occurs largely from the top of the casting, which is normally discarded, and the density and RDX distributions of pressure castings produced in the MRL experimental moulds using either recrystallised or milled and boiled RDX appear to be satisfactory. The RDX/TNT/Beeswax compositions derived from recrystallised RDX are less sensitive to shock initiation than are those derived from milled and boiled RDX, but there are indications that they may be more sensitive to impact.
